Non Renewable Energy Source List – A variety of energy sources can be used to power human activities, and this energy must often be transferred from source to destination. Jump to Literacy Energy Principle 4: Find these ideas teaching activities
There are 7 key concepts underlying the teaching of energy sources: 4.1 Man transfers and transforms energy from the environment into forms useful for human endeavours. The main sources of energy in the environment are fuels such as coal, oil, natural gas, uranium and biomass. All primary fuels except biomass are non-renewable. Primary sources also include renewable sources such as sunlight, wind, moving water, and geothermal energy. There are 6 other concepts. View All… Hide 4.2 The use of human energy is subject to limitations and restrictions. Industry, transportation, urban development, agriculture and many other human activities are closely related to the amount and type of energy available. Access to energy resources is limited by the distribution of natural resources, the availability of accessible technologies, socioeconomic policies, and socioeconomic status. 4.3 Fossils and biofuels are organic materials that contain energy captured from sunlight. Fossil fuels such as oil, natural gas and coal derive their energy from energy captured from sunlight long ago by organisms such as plants, algae and cyanobacteria. Biofuels such as food, wood and ethanol derive their energy from energy recently captured by producers from sunlight. The energy stored in these fuels is released in chemical reactions such as combustion and respiration, which release carbon dioxide into the atmosphere. 4.4 People transport energy from one place to another. Fuel is often not used at source, but transported, sometimes over long distances. Fuel is mainly transported by pipelines, trucks, ships and trains. Electricity can be created from various energy resources and can be converted into any other energy. Electrical circuits are used to distribute power to remote locations. Electricity is not a main source of energy but an energy carrier. 4.5 People generate electricity in different ways. When a magnet moves or the magnetic field changes relative to a coil of wire, electrons are forced to flow into the wire. Most human electricity production is done this way. Electrons can also be induced to flow through direct interactions with light particles; This is the basis on which a solar cell works. Other methods of generating electricity include electrochemical, piezoelectric, and thermoelectric. 4.6 Humans deliberately store energy for later use in various ways. Examples include batteries, water tanks, compressed air, hydrogen and thermal storage. Energy storage involves many technical, environmental and social challenges. 4.7 Different sources of energy have different advantages and disadvantages and there are different ways in which energy can be converted, transported and stored. A given energy system, from source to sink, has an inherent level of energy efficiency, financial cost, and environmental risk. Each system also has national security, access and equity implications.
As oil resources become scarce, exploration pushes the limits of what is technically possible, such as deep-water offshore drilling.

An energy transformation is taking place. The 2016 Paris climate agreement sent a clear signal that a global shift to low-carbon energy is essential. Despite plans to withdraw the United States from the Paris Agreement, the transition to clean energy, led by American states, cities – large and corporations – as well as other countries around the world continues.
The origins of our energy supply is an interesting and engaging topic for students and a great way to learn about the different ways energy can be created, as well as the social impact and impact of different forms of energy. These concepts revolve around energy used for human purposes including renewable and non-renewable energy sources, energy storage, power generation and transportation of energy from one place to another.
An essential starting point for this topic is the concept of renewable energy sources and non-renewable energy sources. Most students are already familiar with the idea that fossil fuels regenerate at a much slower rate than we use, so they are not renewable. Renewable energy comes in many forms: hydro, solar, wind, geothermal and biofuels. Each of these presents a range of relevant topics and nuances. For example, solar energy can be generated on a single roof or on large, utility-scale solar farms. Solar power can also be created in ascending solar plants, which use a series of mirrors to focus solar energy onto a central tower. This type of solar energy can provide electricity even at night. A detailed study of energy generation can avoid overly simplistic labeling of certain types of energy as good or bad.
It is also worth dealing with the practical and technical aspects of energy. The distribution of energy resources around the world is uneven, as some regions have abundant energy resources while others do not. The areas that use the most energy may not naturally be the only places where energy resources exist. For example, rich oil and gas deposits are found in offshore marine environments, while wind farms are found in rural environments. In any case, this energy is transported to a place where energy is consumed. Additionally, energy termination practices vary by geography, time of year, and time of day. Therefore, energy must be transported, stored and converted from one form to another so that it is available when and where it is needed.
Today’s students are witnessing a renaissance in energy technology. After decades of energy use dominated by fossil fuels, a wide range of innovative options await exploration. Weaning the world off carbon-intensive fuels is a high-profile topic that offers rich, relevant and multifaceted learning opportunities. Energy sources can be studied from the perspective of engineering, public health, economics, or international trade—idealizing a multidisciplinary approach (these ideas are also covered in Energy Decisions.)
Just as ecosystems depend on energy input, human societies also depend on energy for infrastructure, transportation, food, and many other human activities. However, there are limits to the amount of energy available to a given society. Even renewable energy models depend on geographic location and technological availability. Non-renewable energy resources are limited and affect their extraction, transportation and consumption. Energy prices, energy equity and energy security are all factors that determine the availability of energy in different segments of society. Some societies have an abundance of energy, while others struggle to meet their basic needs. By learning about these concepts, students can begin to see how people are responsible for energy use, but also limited by the practical aspects of energy use.

Most students already understand that energy can come from many sources. However, they may have a misunderstanding of where their own energy comes from or how much energy they receive from different sources. For example, students may be surprised to learn that only a small fraction of the US energy supply comes from wind turbines and other renewable sources (11% in 2018), while ‘80%’ comes from fossil fuels. Nuclear power provides 8% of the US energy supply (Energy Information Administration, this page is updated annually). Despite the popularity and importance of renewable energy technologies, it is important to understand that fossil fuels still make up the majority of our energy portfolio and are expected to remain so for decades (Source: Energy Information Administration, 2020).
This highlights the incredible challenges we face in moving beyond fossil energy. Moving away from fossil fuels will bring a new set of questions, such as energy storage, battery technology and an energy source woven from many intermittent sources rather than a few state-owned power plants.
Today’s students seem excited about renewable energy, and it’s a great way to engage them. But it is important that they learn about the challenges and realities of restructuring the energy system. For example, consider another new energy structure – large renewable energy plants and wind turbines, solar farms or bundling supplies – required to replace 80% of the energy supply from fossil fuels. Numbers are important. A quantitative treatment of these topics makes it clear that we have a long way to go to ensure a safe, secure and clean energy supply.
Like most subjects we teach, our energy future is a problem with no definitive answer. This can be an interesting call to action for students. Maybe they will be part of the solution design? The Next Generation Science Standards emphasize engineering, design, interdisciplinary thinking, and problem solving. These ways of thinking are essential to meeting this challenge.
